Abstract

PURPOSE:To perform a confirmation test equivalent to an actual load by operating a thyristor inverter in parallel to a commercial power source and by adjusting its voltage and phase as well as a feedback load method for the load test of a transformer. CONSTITUTION:The output frequency of the inverter part 202 of an inverter 2 is equalized to the ocmmercial frequency of a commercial power source 1. When an electromagnetic contactor 8 is turned on while the output voltage V1 of the inverter 2 and a commercial power source voltage Vs are in phase with each other, a current Io flows according to those voltage, their phase difference and a reactor 7. When the voltage Vs and its phase are fixed, this current Io is optionally variable by adjusting the inverter output voltage VI and its phase. For this purpose, the phase phi and voltage VI are adjusted to adjust and set the power factor of the inverter and the value of a load, so the test is carried out by simple facilities without large energy consumption.
